DETAIL DESCRIPTION OF THE INVENTION Referring now in detail to the drawing, 10 designates an extension table embodying the invention. The same comprises a hollow, transverse, central vertical support 11. The support 11 may have parallel, opposed, vertical walls 12 interconnected by parallel vertical, side walls 13. Between walls 12 and 13 is a horizontal bottom wall 14 and a horizontal top wall 15. The walls 12 and 14 are formed with a pair of lower, vertical slots 16 and said walls 12 and 15 are formed with a pair of upper, vertical slots 17. Slots 16 and 17 are in vertical alignment.

Extending through the slots 16 are lower, parallel, coextensive rectangular oor engaging metal tubes 18. The tubes 18 each has an upper wall 18a, a lower wall 18b and side walls 18C. Within each of the lower tubes 18 is a wooden board 19. `Each wooden board 19 is formed at its underside with a central notch or cutout 20, forming inner side shoulders 21 and a horizontal under-edge 22. The notches 20 are located below the hollow space 25 within the hollow support 11. Fixed within the hollow support 11 is a transverse, horizontal wall 26 mounted on the top of the tubes 18 and formed with pairs of vertical openings 27, disposed between the walls 12. The top wall 18a of each tube 18 is formed with openings 28 registering with the openings 27. The portion of each board 19 disposed above the notch 20 is formed with vertical through openings 29 registering with the openings 28 and 27. Contacting the underside of the surface 22 of the notch 20 is a metal plate 30 formed with openings 31 registering with the openings 29. The purpose for the plate 30 and the openings 27, 28, 29 and 31 will appear hereinafter.

Extending through the upper, parallel slots 17 are upper metal tubular members 40. Each tubular member 40 has a bottom wall 40a, a top wall 40b and side walls 40C. Disposed within the hollow space 25 is a horizontal, transverse wall 43 contacting the undersides of the lower surfaces 40a. Members 26, 43, 12, 13, 14 and 15 are all interconnected rigidly by means of glue, screws or other fastening means.

Blocks 45 may be interposed between the walls 14 and 26 and contact the side walls 13. A wall 46 is attached to the underside of the wall 15 and located between the inner side walls 40C of the tubes 40. Walls 47 contact the underside of wall 15 and are interposed between the outer ide walls 40C of the tubes 40 and the side walls 13. Blocks 8 may be interposed between the ends of walls 43 and 1e undersides of walls 47. Wall 43 has openings 50 aligned 7ith the openings 27. The lower walls 40a of tubes 40 re formed with opening 51 registering with the openings 0. Inside of each upper tube 40 and resting on the lower lbe wall 40a is a metal plate 60 disposed centrally above 1e transverse hollow support 11. Plate 60 is attached to 1e lower tube wall 40a by means of screws 61. Said plate is formed with a pair of threaded openings 62 register- 1g with openings 63 in the bottom wall 40a, which openigs register with the openings 50 in wall 43.

Tie rods 64 pass through the openings 31, 29, 28, 27, 0, 63 and 62. The upper ends of the tie rods 64 are dreaded and are screwed into the threaded opening 62. .`he lower ends of the tic rods 64 are screw threaded and tuts 52 screwed thereto contact the underside of the plate y0. Thus the tubes 18 and the boards 19 are firmly coniected to the central support 11 and to the upper tubes 40.

Said upper tubes extend to opposite sides beyond the ower tubes 18. The lower tubes 18 may be supported on ollers 70 which contact the floor. The casters 70 are referably connected to the outer ends of the tubes 18.

The tubes 18 are coextensive with the wooden board 19,y

For the purpose hereinafter appearing, the bottom walls lila of the upper tubes 40 are formed adjacent the outer :nds thereof with openings 73. The openings 73 may be ival, round or of any other suitable shape.

Attached to the ends of the walls 40a, and spaced invardly of the openings 73 are upstanding stop pins 74 for ,he purpose hereinatfer appearing.

Slidable in each of the outer ends of the upper tubes l0 are parallel extension members 75. Vhen the extension nembers are moved inwardly toward each other they will :ontact opposite side edges 60a of the plate 60. When said :xtension members 75 are wholly within the tubes 40, :he outer ends 46 are located substantially at the ends of raid tubes. Said extension members 75 are rectangular in :ross-section, the same as the tubes 40. Said extension nembers 75 are formed at their undersides with longi- :udinal slots 78 terminating short of the ends thereof.

The pins 74 project upwardly into the grooves 78. When the extension members 75 are pulled all the way out, the pins 74 serve as stops engaging the inner ends of grooves 78 to limit outward movement. At the outer ends of the grooves 78 are enlarged spaces 79 each terminating in an and inner abutment surface 80. When the extension members 75 are wholly within the tubes, the spaces 79 are disposed above the opening 73. To pull the extension members outwardly, the operator inserts a finger upwardly through an opening 73, engages the abutment surface 80 at the outer end of the groove and pushes the extension member sufficiently outwardly so that it may be gripped from the outer end and pulled out.

A table top 90 having a width preferably greater than the central support 11 may be mounted on the upper tubes 40 by means of soft plastic discs 91 attached to the top walls 401) of the tubes, adjacent the outer ends thereof. The discs 91 may be made of vinyl or nylon and are preferably soft and frictionally engage the underside of the table top.

The table top 90 may be made of glass or any other suitable material.

The table may be used without any extension leaves and in such event the extension members 75 remain within the tubes 40. However, the extension leaves 95 may be employed to increase the length of the table. Each extension leaf 95 is preferably a rectangle and of the thickness of the table top 90 and also of the width thereof.

Attached to the underside of each extension leaf adjacent the outer end is a spacer member 96. Each member 96 has a top wall 97 screwed or otherwise attached to the underside of the extension leaf and an end flange 98 to engage the outer edge 96 of the extension 75 and side flanges 99 engaging the side surfaces of the extension 75. Extending downwardly from the top Wall 97 is a pin 100 which may engage in a socket or bore 101 in the extension 75. The pin 100 thus locates the extension 9S in proper place and also spaces the extension leaf above the extension 75 and in the plane of the table top 90.

Spacing members 103 are attached to the undersides of the extension leaves 95. It will be noted that the table top extends a short distance beyond the outer ends of the tubes 40. The members 103 are attached to the inner ends of the extension leaves 95 and each has a top wall 104 screwed or otherwise attached to the underside of the extension leaf, and side flanges 10S contacting the side surfaces of the extension member 75. Members 103 also have inward reduced projections 106 which engage beneath the table top and these are of a thickness somewhat greater than the thickness of the upper walls 40b of tubes 40. Thus members 96 and 103 serve to retain the extension leaves 95 in the plane of the table top.

It will thus be seen that there is provided an article in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.

As possible embodiments might be made of the above invention, and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings, is to be interpreted as illustrative and not in a limiting sense.
